9P149 vehicle with 9M144 missiles of anti-tank complex «Shturm-S» in Saint Petersburg Artillery museum.
Iraqi MT-LB converted into a SPAAG armed with a ZU-23-2 anti-aircraft gun.
The MT-LB amphibious armoured tracked vehicle is fully amphibious, propelled in the water by its tracks. The low-silhouette MT-LB has a flat-track suspension consisting of six road wheels with no return rollers. The box-like welded steel plate hull has a crew compartment at the front, engine immediately behind on the left side, and a troop compartment at the rear which has inward-facing folding canvas seats for 10 infantrymen. The flat hull roof has two forward opening troop exit hatches. The infantry enter and leave the vehicle by two rear doors which are provided with firing ports. The total of four firing ports also include one on each side of the vehicle. The small turret to the right of the commander’s position mounts a single 7.62-mm machine gun. Standard equipment on all vehicles includes an NBC protection system.
The MT-LB is an amphibious armored tracked vehicle with a low-silhouette, box- like hull made of welded steel plates and a small turret on the right front, mounting a single 7.62-mm machine gun. There are four firing ports, one on each side of the vehicle and one in each of the two rear exit doors. Two additional, forward-opening, troop exit hatches are located on the flat hull roof. The flat-track suspension consists of six road wheels with no return rollers.
The MT-LB can employ an extra-wide-track with an “aggressive” grouser to make over snow and swamp operations easier. The wide-tracked version, designated MT-LBV, has a track which is 565 mm wide compared to the normal 350-mm-wide track. The wider track reduces ground pressure from 0.46 to only 0.28 kg/cm2.
The MT-LB is a multipurpose vehicle. When used as an ARC or command vehicle, it can carry ten personnel besides its two-man crew (driver and commander-gunner). It also is used as a prime mover for various types of artillery. In this case it can also carry the artillery crew (six to ten personnel). It is frequently used as prime mover for the 100-mm antitank gun T-12. As a cargo and general transport vehicle, it has a cargo capacity of 2.0 metric tons (towed load 6.5 metric tons). The wide-tracked MT-LBV is used as a soft-terrain vehicle.
The MT-LB is lightly armed and lightly armored.
The MT-LB was first designated M 1970 since it was initially identified by the West in 1970. Its design is based on the MT-L light transport vehicle and prime mover. The MT-L, which is unarmored and turretless, was first developed for geological research in the far north.
The crew, a driver and a commander/gunner sit in a compartment at the front of the vehicle, with the engine behind them. A compartment at the rear enables up to 11 infantry to be carried or a cargo of up to 2,000 kg. A load of 6,500 kg can be towed. The vehicle is fully amphibious, being propelled by its tracks in the water.
A small turret at the front of the vehicle fits a 7.62 mm PKT machine gun with 360 degree manual traverse and an elevation of -5 to +30 degrees. The vehicle is lightly armoured against small arms and shell splinters with a thickness of 3 to 10 mm of steel. The infantry compartment has two hatches over the top, which open forwards. There are four firing ports – one in either side of the hull, the other two in the rear twin doors of the infantry compartment.
The driver is provided with a TVN-2 infra-red periscope, which in combination with the OU-3GK infra-red/white light search light provides a range of about 40 m. All vehicles include an NBC system.
